Ecological Economical Zoning of Minas Gerais
Introduction
ZEE → Zones subject to a certain model of use according to
degrees of natural vulnerability and social potentiality.
ZEE-MG → implemented by the Government of Minas Gerais to
support policy making by means of a statewide diagnosis of
economical, social, ecological and biophysical sustainability.
NATURAL VULNERABILITY → the capacity of resisting or
recovering from impacts caused by human activities.

Ecological Economical Zoning of Minas Gerais
Objectives
to investigate alternative methods of spatial inference, viz. fuzzy
logic and neural networks for generating maps of vegetation
vulnerability for the State of Minas Gerais, and
to evaluate their suitability to be used instead of weighted
overlay.

Study site and data sets
The study area comprises the whole State of Minas Gerais.
Data compiled and included in the ZEE-MG were structured in a
GIS using the raster data model with a spatial resolution of
270x270m.
Indicators of vegetation vulnerability were derived from a
30x30m resolution land cover map (Scolforo & Carvalho, 2006)
and from priority conservation areas (Drummond et al., 2005)
